21st Amendment Marooned on Hog Island

21st Amendment Marooned on Hog Island

When life gives you oysters, be sure to brew some killer oyster stout.


That’s exactly what Nico Freccia and Shaun O’Sullivan, co-founders of 21st Amendment Brewery did. In a food+beer collaboration with Hog Island Oyster Company co-founders, John Finger and Terry Sawyer, the 21st Amendment Brewery team has created Marooned on Hog Island, the latest beer in their Insurrection Series, a limited edition, once-in-awhile four-pack release of a very special beer that rises up in revolt against common notions of what canned beer can be.


Marooned on Hog Island has an ABV of 7.9% and was brewed using Magnum and Willamette hops with an ale yeast, a variety of malts including Pale, Crystal, Chocolate and Carafa, Rolled Oats, White Wheat and the kicker: 450 pounds of Hog Island Sweetwater oyster shells.

4.3 Smell is great roasted sweet malt...taste is the same...smooth with good sweetness and less bitterness..high flavor and very nice black/dark red appearance...medium complexity...could drink a couple in a row...but def a heavier beer without watery finish
3.1 Opaque brown. Full body, flavorful, smooth texture, long taste. Bitter moderately, dryish, crisp. Roasty flavors, coffee, dark chocolate. Well rounded, enjoyable, not exceptional.
3.4 Pour is a black with a small tan head. Aroma is roasted malt a little black licorice and some sea salt brine. Flavor is a nice roasted malt with chocolate and coffee notes. A nice roast and salinity is left on the tongue. Not a over the top rich and roasted stout but plenty flavorful with some brine fron the oyster shells giving this beer a little something extra.
3.8 Some rpast amd caramel with a touch of oyster saltiness. Black pour with great head and lacing. Bittersweet finish. Tap at Snally.
3.5 Tallahassee, Fl - Momo’s Pizza - Northeast - on tap. Viscous, dark black, motor oil-like pour - light mocha colored head. Olive oil and topsoil in the aroma, but otherwise pretty neutral. Bittersweet chocolate, some topsoil, a touch of pipe tobacco, a slight whisper of licorice. Slick mouthfeel that thickens as it warms. Pretty decent.
4.5 Taps coffee sable with a thick tan head. Aroma offers molasses, roasted malt, quality coffee, and semi-sweet chocolate plus a snip of oyster. Flavor nicely echoes the aroma while emphasizing chocolate and oyster. Viscous mouthfeel features good fizz. What better place to get marooned?
3.9 Can courtesy of joe. Dark black. Thin head. Dark roasted coffee. Slightly salty. Wish they did more stouts. Not really getting the oysters, so it must be working well. Very easy drinking.
3.8 Can, 355ml. Opaque dark brown with a foamy brown head. Aromas of roasted malts, molasses, plums, alcohol. Full bodied, fizzy carbonation. Medium sweet, medium bitter. Deep roasted flavors into a stinging bitter finish. Very pleasant toasted aftertaste. Seems watery but really isn’t, its just the oyster stout profile.
4.2 It’s safe to say this isn’t a Vegan friendly beer. I’m not sure how the oyster shells are used, and I probably don’t want to know. Good standard Stout flavor, but am I crazy, or is this beer slightly slimy?
3.7 Aroma is dark/roasted malts, chocolate and a hint of fruit/citrus. The flavor is fruit, dark/roasted malts, chocolate and big acidity/slight brininess in the finish.
3.6 Pours a black with smooth, light tan head that lingers for a bit. The aroma has mostly chocolate and coffee, with some lesser degrees of oysters, roasted malts, salt, and hints of vanilla. The taste is salty, with a healthy dose of coffee. I find chocolate, caramel, and still a bit of coffee. Aftertaste is a salty coffee flavor sticks with you for awhile. This one is medium in body, with a creamy texture, and some subtle carbonation. The saltiness makes this different than the usual.
3.9 Pours a handsome opaque cola with fluffy chocolate milk head, a good size and lasts for a bit. Nose is coffee with a bit of burnt toast. Palate reinforces coffee, occasionally in espresso bean bitterness, but cocoa and a hint of dark fruit peek out. A bit of hop bitterness, but fortunately it’s in line with the coffee profile, not dominating it. There’s even an offsetting hint of dark fruit. Where are the oysters? Well, the slick mouthfeel gets balanced by a touch of brine, making for a pleasant experience.
4.2 Black with a thick tan head. Aroma is roasted coffee. Flavor is roasted coffee with a silky body and a bitter finish.
4.0 Smooth chocolate aroma that’s not overwhelming. Black bodied with finger thick tan head. Mellow chocolate roasted malt taste. Has a slick feel to it’s full body. Smooth to the finish.
3.9 Purchased at Bottles and Cans in Chicago, IL; enjoyed on a relatively nice late March Tuesday night listening to records. Appearance is pitch black, moderate tan head that quickly dissipates. Aroma of chocolate and oysters, also a bit of espresso, smells nice. Taste equally nice, good chocolate profile, bit of nuts, definite oysters which is unique. I’m liking this one.
3.7 Can at Hog Island with BBQ Oysters. Creamy nose, lots of umami, light oyster, cocoa, some coffee. Nice body. Hides the alcohol well.
4.7 Pour is a dark purple with red and brown accents to it. Very low carbonation, no head or anything. Looks like an oil slick. Smell is sweet ocean air, cut grass, vanilla, very sweet. Taste is similar: a light and balanced sweetness with roast and malt in the background.
3.7 On tap @ 21A San Leandro. Cola colored beer with a khaki head. Huge roasted malt and cocoa powder nose. There’s some nice fruity qualities to it as well. Sweeter than expected with flavors of fudge and hazelnut, but some nice enough bitterness on the back end. Hints of coffee, subtle brine and mineral notes, and some burnt toast. One of the better 21A beers I’ve had in awhile.
4.1 Shared can with a Christmas movie. Delicious. One of the best oyster stout I’ve ever tasted. Just the right amount of roasty notes. Really smooth, medium mouthfeel. Hops add bitterness but don’t overpower with citrus/floral/pine. The oyster shells make it- super briny. Tastes like my hair after surfing. Delicious.
3.8 Aluminum can from Sprout’s: Poured an opaque dark brown liquid that created a monstrous sizing of foam. Aroma is mild with hints of roasted malts, sugary marshmallow, and cocoa powder. The drink is mostly bitter with influences of chocolate and cocoa nib while the palate is smooth and oily. Very dry residue left behind in the finish. For sure taste like an oyster stout and was extremely well balanced body.
2.4 Can to snifter. Pours dark black, small head, off white. Aroma is malt, salt, seaweed. Taste is very minerally, touch of caramel like sweetness at the end, but mostly bitter and dry. Feel is light and thin. Good carbonation for a stout. Not great overall, but enjoyable enough. Can’t see myself buying this again.
3.8 Can from Beer and Wine. Dark brown body with huge, tan head. Nose is sweet, caramel, chocolate. Taste also caramel, malts, chocolate and definitely oyster tastes in there as well. Just really good stuff. Slivery, oily texture in the finish.
3.4 Can, black beer, almond colored head, good lace. Aroma is roasted malt, wet dog, and smoke. Taste is toasted barley, hint of vanilla, coffee. Palate is medium heavy, smooth and rich, carbonation almost nitro like. Finish is dry and roasty.
3.5 Pours a deep brownish black from the can with fluffy tan head that dissipates to leave moderate lace. Aroma of sweet and roasty malts with a hint of earth. Taste follows, nice stout, no real brine to me.
3.6 Old rating. Pretty brown color. The taste is a creamy mix. Some dark malts, chocolate, sea salt, slightly briny (could be in my head) and decent dose of dry, bitter hops. Interesting, but I hoped for something a little bigger in my first oyster stout.
3.3 "Looking forward to this. Ended up ok but not what I’d hoped. The saltiness is there but really not the cool brine and chocolate roast combo I expect from a good oyster stout. Pretty big foreign type stout, big roasted malts and malted chocolate, decent bitterness. Not bad but likely a one timer."
3.8 Transfer from BA review on 1-3-13- Served on tap in a 10 oz chalice glass Appearance – Served a deep-deep brown nearly pitch black brew with a one finger cream colored head. The head had a decent retention fading over time to give a nice level of lacing on the sides of the glass. Smell- The aroma was an odd mix of roasted, sweet and slightly sea like smells. The sweeter smells were of a chocolate and caramel nature with the “sea like” smells being of a saltwater beach like aroma. While saltwater like, it was not unpleasant and it actually melded quite well with the sweet and roasted smells. Taste – The taste begins as most other stouts’ do, with a roasted malt and slightly sweet taste. The roasted flavors were a mix of toasted barely and some dark chocolate with the sweet being largely of a caramel nature. As the taste advanced however the roasted flavors begin to dwindle some with the sweet increasing slightly as a molasses and vanilla flavor come to the tongue. While this is occurring, there is also a more salty flavor developing in the taste. While light at first it gets stronger and stronger as the taste advances. In the end the sweet and salty tastes along with a nice roasted malt flavor have control over the tongue and leave a rather salty roasted flavor to linger on the tongue. Mouthfeel- The body of the brew was on the average side in terms of creaminess (maybe a little above) with a carbonation level that was average as well. Overall though I think the blend of medium body and medium carbonation suited the somewhat opposing (at least in feel) sweet and salty aspects of the brew against the roast flavors of the brew quite well. Overall- A rather tasty stout. Although it is not something I would take again and again due to the slightly more salty nature in the taste, it is a rather unique and different flavor to try. This is one I think people should experience I they get a chance.
3.6 12oz can. Poured a deep brown color with an off white head. Roast, some chocolate, little earth, and some nuts
